Attention! The dependence of the flow rate Q on the pressure P is given by the equation: Q = K√10P, where Q is expressed in liters / minute and P in megapascals.

Possibility of implementation

52 valve with slant reduction

Hydrant can be connected to DN52 water supply due to 52 valve with slant reduction

Connection of hose connecting hydrant valve with water axis – standard

  • thread connection in standard
  • connection by adapter and hose coupling

Nozzle crimping

  • nozzle crimping with aluminum sleeve in standard
  • nozzle crimping with brass sleeve
